Title: Aluminothermic process
IPC: C22B5/04
Filed: 1976-05-21
Abstract: 1531152 Aluminothermic process ATOMIC ENERGY BOARD 21 May 1976 [28 May 1975 (2)] 21020/76 Heading C7D The aluminothermic reduction of reactive (Ta, Nb, Ti, Zr, Hf, Mo, Cr, V) metal oxides comprises melting a conductive susceptor metal in a vessel within an induction furnace and adding intimately mixed pellets of the reactants, containing freely divided oxide of the reactive metal, aluminium, and optionally a slagging agent, i.e. CaO, and controlling the power input to the melt such that the temperature remains above a predetermined minimum. The vessel may be an Al 2 O 3  crucible or a water cooled copper crucible and the reduction may be carried out in an inert (Ar) atmosphere. Since the exothermic aluminothermic reaction in some cases may be inadequate to maintain the metal and slag formed in a molten condition, the use of the additional heat from the induction furnace permits the liquid state to be maintained and a satisfactory separation of the two components. The resultant reactive-metal aluminium alloy may be further heated in an electron-beam furnace or by other suitable methods to recover the reactive-metal in a pure state. Recovery of Zr and Ti is exemplified.

Title: Process for the control of electric current impulses for the purpose of remote picture transmission or of television or the like
IPC: H04N1/407
Filed: 1928-07-20
Abstract: 320,673. Fulton, O. July 20, 1929. Copying-telegraphs. -In a copying-telegraph transmitter in which current impulses having a sudden rise and fall are converted. into, or produce or control, similar impulses having a comparatively gradual rise or fall, the characteristics of the rise and fall are varied without altering their limiting values. An exploring apparatus 12 is connected in series with a potentiometer 11, a resistance 13, and a resistance 14 shunted by a condenser 15. The time of charging and discharging the condenser, and hence the characteristics of the voltage applied to the grid of a thermionic valve 16, are varied by an adjustable tapping on a resistance 14. Such a single control alters the proportion of the resistance 14 to that of the circuit and thus the limits of the potential applied to the grid of the valve. This is compensated by a variable tapping on the potentiometer controlled in common with that on the resistance. Switches are provided to reverse simultaneously the connections to the potentiometer battery 10 and to a grid bias battery 17 to facilitate the transmission of positive or negative pictures. The anode circuit of the valve includes an air-cored transformer 21 supplied with low-frequency oscillations by an oscillator 22. The transformer is loosely coupled to reduce damping of the carrier wave and is tuned by a variable condenser or a tapped bank of condensers 23. The modulated lowfrequency oscillations are taken from the anode circuit to a transmitting- circuit by an air-cored transformer 24. Specification 298,621 is referred to in the Provisional Specification.

Title: Improvements relating to the moulding of plastic articles
IPC: B29C33/60
Filed: 1961-06-14
Abstract: In a process for moulding articles from thermosetting resins such as polyurethane which, during curing would, if not prevented from so doing, initially adhere to the mould, but become non-adherent as the cure proceeds, the surface of the mould is coated with a film of thermoplastic material, e.g. wax, the uncured resin being introduced into the mould at a temperature below the melting point of the thermoplastic material and the mould maintained below said temperature, which is within the curing range of the resin introduced, until the cure has reached the point at which the resin is non-adherent to the mould.  The temperature is then raised to accelerate the cure and soften or melt the thermoplastic film so that when the cure is complete the moulded article may be easily removed from the mould.

Title: New compounds and process for preparing them
Inventor: WHITE GERALD NOEL
IPC: G03C7/36
Filed: 1961-06-16
Abstract: Aryl amino acid compounds useful as colour couplers are prepared by condensing an aryl amino ester, preferably a compound of the formula NH2R-COOR1 (in which R represents a benzene residue which may be substituted with 1 or more carboxy, alkoxy or alkyl groups and R1 is an alkyl group containing 1 to 5 carbon atoms, with a malonic acid di-alkyl ester preferably containing 1 to 3 carbon atoms in the alcohol moiety e.g. dimethyl or diethyl malonate, and subjecting the resulting product to hydrolysis under alkaline conditions.  The condensation of the malonic acid dialkyl ester with the aryl amino ester is preferably carried out at a temperature between 150-190 DEG C. and preferably in the presence of a condensation catalyst e.g. a tertiary organic base such as triethanolamine, pyridine, dimethyl aniline or collidine. Specified aryl amino esters are methyl or ethyl p-aminobenzoate, methyl or ethyl m-aminobenzoate, methyl 3-amino iso-phthalate and ethyl 2-methoxy -4- aminobenzoate.  The compounds may be used as colour couplers, as such, or in presence of an adsorption means to prevent diffusion such as a long chain fatty acid e.g. lauric or stearic acid. Preferably, however, the compounds are acylated with an acylating agent, for example, either by reaction with a long chain fatty acid halide preferably containing 10-20 carbon atoms e.g. lauroyl or stearoyl chloride preferably in the presence of a tertiary organic base or inorganic base, e.g. sodium or potassium hydroxide or pyridine or dimethyl-aniline or by direct fusion with a long chain substitution derivative of succinic anhydride e.g. hexadecenyl succinic anhydride or octadecenyl succinic anhydride. In an example ethyl-p-amino benzoate is reacted with diethylmalonate in the presence of pyridine and the product substantially treated with aqueous caustic potash to produce.  This compound may be treated with lauroyl chloride or octadecynyl succinic anhydride. In another example 3-amino-izo-phthalic acid dimethyl ester is reacted with dimethyl malonate and the product subsequently treated with caustic soda.
